Ripple
A lot of parents install a control app and find a few days later that their kid uninstalled it, or moved the system clock forward and the limits stopped working. Others take the phone away completely and then the child cannot message home. This page lists age-based setups for Ripple on the Android phone your child already has. The focus is uninstall protection, clock tamper protection, and blocking only short video feeds so normal chats keep working.
These are common starting points. Adjust them to your child.
No. Ripple times cooldowns and focus sessions with a monotonic clock that counts from boot, so changing the date or time in system settings does not shorten them.
With device admin on, uninstalling first requires going through the release flow inside Ripple. On Android 11 and later you can also enable an on-device wireless debugging guard with no PC. It locks the system uninstall switch and brings the service back about 2.5 seconds after the app is swiped away from recents.
Yes. Ripple blocks only the short video screens inside YouTube, Instagram and WeChat. Messages, calls, long videos and online classes keep working.
The parent keeps an emergency unlock code. Without the code, any change that loosens the rules has to wait out a 15-minute cooldown.
No. Ripple is an 8.57 MB Android app that installs on the phone your child already has. It is free, has no ads, needs no account, and keeps all data on the device.
